Note:
These bit and flags can be read out but cannot
be written.
(6) START Condition Generating Method
When the ES0 bit of the I
2
C control register (address 00F9
16
) is “1,”
execute a write instruction to the I
2
C status register (address 00F8
16
)
for setting the MST, TRX and BB bits to “1.” Then a START condi-
tion occurs. After that, the bit counter becomes “000
2
” and an SCL
for 1 byte is output. The START condition generating timing and BB
bit set timing are different in the standard clock mode and the high-
speed clock mode. Refer to Figure 43, the START condition generat-
ing timing diagram, and Table 8, the START condition/STOP condi-
tion generating timing table.
(7) STOP Condition Generating Method
When the ES0 bit of the I
2
C control register (address 00F9
16
) is “1,”
execute a write instruction to the I
2
C status register (address 00F8
16
)
for setting the MST bit and the TRX bit to “1” and the BB bit to “0”.
Then a STOP condition occurs. The STOP condition generating tim-
ing and the BB flag reset timing are different in the standard clock
mode and the high-speed clock mode. Refer to Figure 44, the STOP
condition generating timing diagram, and Table 8, the START condi-
tion/STOP condition generating timing table.
